description validation
2015/9/9
The CYCLOPES project aims at providing high level biophysical products such as LAI, fAPAR, fCover over
the globe at 1 km spatial resolution at a 10 days time interval. To provide continuity over long...
Ground measurements of photosynthetically active radiation (PAR) balance and leaf area index (LAI)
are required for validating, and sometimes calibrating biophysical products derived from satellite

Abstract气候变化对植被动力学有非常大的影响。为了定量描述气候变化对植被的影响，文章利用MODIS fAPAR 数据和NCEP 的净辐射和降雨再分析数据对青藏高原地区气候变化对植被的影响进行了时间序列分析。研究所用的数据时间跨度为2000年至2005年。首先利用NCEP 再分析数据建立了干旱度因子的时间序列，为了与MODIS fAPAR 具有相同的时间采样间隔，由NCEP的日净辐射和日降雨量...
